raketilised

Rakaelised are a fictional alien species from the science fiction novel "The Martian" by Andy Weir. They are encountered by the protagonist Mark Watney on Mars. The rakaelised are described as silicon-based life forms that have adapted to the harsh Martian environment. They are characterized by their rocky exterior and their ability to survive in the planet's thin atmosphere and low temperatures.

Unlike carbon-based life, the rakaelised are thought to metabolize minerals and utilize geothermal energy for sustenance. Their physiology allows them to endure extreme conditions that would be lethal to terrestrial organisms. The novel suggests they may exist in a dormant state for long periods, only becoming active when conditions are favorable. Their intelligence and societal structure are largely unknown, as Watney's interactions with them are limited and primarily focused on survival. The rakaelised serve as a narrative element to highlight the potential for life beyond Earth and the unique adaptations required for such existence. Their presence introduces a speculative biological element to the story, prompting contemplation about extraterrestrial life forms.
